Quantum circuit representation and incomplete Bell measurements in Compton scattering
Wei Xie, Yu-Chen Guo, Shuang Li +1
We formulate massless tree-level Compton scattering as an effective two-qubit operation on electron and photon helicities. In the Bell basis, the scattering map separates into two…
Probing Neutral Triple Gauge Couplings at e- p colliders
Xue-Jia Cheng, Chong-Xing Yue, Ji-Chong Yang +1
The Standard Model Effective Field Theory~(SMEFT) has attracted much attention as a model-independent way for probing new physical signals. In the SMEFT framework, collide…
Enhancing the sensitivity to FCNC top decays and in the boosted regime at CLIC
Shuo Yang, Peng-Bo Zhao, Ji-Chong Yang
The top quark, having the largest Yukawa coupling to the Higgs sector, provides a unique window into electroweak symmetry breaking and possible new physics beyond the Standard Mode…
State-Dependent Visibility of Non-Commutative Ordering in Quantum Dynamics
Ji-Chong Yang, Gui-Qi Hu
A nonzero commutator proves that two orderings differ as operators, but it does not ensure that a physical state can reveal the difference. We ask when non-Abelian ordering informa…
SMEFT-Pheno-Agent: a natural-language-driven AI agent for machine-learning-assisted Standard Model Effective Field Theory phenomenology
Yu-Chen Guo, Jie Wang, Ji-Chong Yang
We present SMEFT-Pheno-Agent, a Python workflow guided by a natural-language AI agent to perform machine-learning-assisted Standard Model Effective Field Theory (SMEFT) phenomenolo…
Expressibility and trainability of a two-dimensional pairwise quantum-circuit ansatz
Shuai Zhang, Wei Liu, Ji-Chong Yang
Parameterized quantum circuits~(PQCs) constitute a central building block of variational quantum algorithms~(VQAs) and quantum machine learning~(QML) methods. Existing ansatz desig…
A collider as a quantum computer
Wei Xie, Ji-Chong Yang
Scattering processes in high-energy physics are inherently quantum mechanical, yet are typically analyzed at the level of final states, where entanglement appears as a property of…
